 Pseudoniouojiteras InnuhUus Blekker, Ac. Roy. Sci. Aiiist., 187(3, p. 47; Japan; 

 Singapore. 



Head 2i in length without ejuulul; depth 3; dorsal XIII, 12; anal 

 III, 8. Scales 39; pores of lateral line 23. Ej-e 5 in head; interor- 

 hital -l-i; snout 2^; maxillaiy 2^. 



Lower jaw not projeetino-; symphyseal knob well developed; tip of 

 lower jaw fitting into a deep, toothless, rostral notch, but without 

 teeth developed in a knob at tip. Palatines toothless; vomer with a 

 trianoultir patch of teeth; moderate bands of villiform teeth in jaws. 

 Maxillary reachino- to below anterior edge of pupil; backward extend- 

 itio- processes from premaxillarics forming a conspicuous bunch on 

 snout, and making a notch in upper protile between them and raised 

 supraorbital rim. Nasal spines small and sharp; preocular spines 

 when present very small, sometimes absent; a small knob of bone 

 present just l)ehind preocular spine on supraorbital rim, to which 

 supraorbital filament is attached; a rather sharp, triangular, postocu- 

 lar spine present; parietals with veiy high sharp ridges ending in a 

 spine; a nuchal spine close behind; 2 spines behind eye in a line with 

 lateral line; suborbitals with a slight ridge broken up into 2 small 

 spines; preopercle with 3 spines and a rudimentar}" one below; the 

 u})per one the largest. Preorbital with an anterior low rounded lobe 

 and 2 angulated tilament-bearing lobes behind; no spines. Interor- 

 bital space very deeply concave and with two slight ridges, between 

 which is a shallow wide channel. Supraorbital filament small in the 

 adult, long in young examples (in a specimen IT cm. in length the}' 

 are as long as the interorbital width); a long filament on posterior 

 angle of preorbital, longer than diameter of eye, and a smaller one, 

 scarcely a third as long, on angle at middle of lower edge of preor- 

 bital; 2 filaments on lower edge of preorbital; a filament on posterior 

 edge of anterior nostril. Gill-rakers very short, 10 of them on 

 anterior limb of arch. Snout, occiput, mandible, maxillaiy, and inter- 

 o})ercle naked; opercle, cheeks, and interorbital with scales; the scales 

 on interorbital very fine. 



Length of pectoral varjdng with size and sex; in male examples 21 

 cm. in length it reaches to middle of caudal I'ays, in those from 14 to 

 10 cm. it reaches to the tip of the caudal; in a female 21 cm. in 

 length it barely reaches to base of caudal. The tips of the pectoral 

 rays are filamentous in males; in females-a ])road thin membrane, free 

 on the lower edge, extends to the tips of the upper pectoral raj's. 

 Membrane of upper pectoral ray incised about to the basal fourth of 

 the second ray; that of second ray about to basal two-fifths of third 

 ray; that of third to basal two-thirds or three-fourths of fourth; the 

 membrune of the upper 3 rays is incised to flu- next ray below each,
